DEVICE FOR CQNNECTING BANDS T0 WRIST WATCHES Filed Dec. 9, 1935 INVENTOR ATTORNEY Patented Aug. 10, 1937 zbtatlit DEVICE FOR CONNECTING BANDS TO WRIST WATCHES 4 Claims.

This invention relates to improvements in the means for connecting or attaching bands or watch bracelets to the casings of wrist watches, and it is the principal object of my invention to 5 provide a simple and inexpensive connection between the Wrist band ends and the watch casings allowing a ready attachment to either a single eye on the watch casing or to a loop or staple on the watch casing, thus providing for a con 10 venient connection of the ends of a wrist band or bracelet to the various types of watch casings without the use of special tools or the necessity of employing skilled labor.

Another object of my invention is the provil5 sion of a simple and inexpensive connection between the ends of wrist bands or bracelets which is durable and highly efficient in use and requires no material change in either the band or the watch casing.

20 These and other objects and advantages of my invention will become more fully known as the description thereof proceeds, and will then be specifically defined in the appended claims.

In the accompanying drawing, forming a mate- 25 rial part of this disclosure:

Fig. 1 shows a connecting member constructed according to my invention with the movable links in closing position.

Fig. 2 is; a View similar to Figure 1, with the 30 connecting links in their open position.

Fig. 3 is a side view thereof.

Fig. 4 is a fragmentary plan view of a watch casing having an eye formed therewith, and illustrates the connecting member combined there- 35 with.

Fig. 5 illustrates a modified form of my invention for connecting the band ends with a watch casing having a staple or loop formed therewith.

Fig. 5a. is a detail view of a tubular member and its eye in front elevation.

Fig. 5b is an end view thereof.

Fig. 5c is a side elevation of one connecting link with its bore and. the eye plate.

Fig. 6 illustrates in plan view the connection of the band ends with a watch casing according to Figure 5.

Fig. 6a is a side elevation of the connection, Figure 6.

Fig. 7 illustrates fragmentarily a watch casing with the connection, Figure 5.

1 As illustrated, the connecting means in Figures 1 to 4 consist according to my invention of 55 an eye a in a plate b to which the band ends are connected in the usual well known manner, not shown, and two connecting links and d which are niovably or rotatably attached to said plate at their outer ends by means of suitable pivot pins or the like, while the inner ends of these links having the forms of heads have oppositely disposed projections or noses e formed therewith which are provided with bores and 9' which also extend through the greater part of the heads and are adapted to receive and hold 10 a threaded pin h when the band is attached to a watch casing.

If the watch casing is equipped with an eye is integral with the watch casing i, the links 0 and d are first swung into the position illustrated in Fi ure 2, and then the projections or noses e are inserted by a suitable lateral pressure into engagement with the eye is (Fig. 4), and finally the threaded pin it is passed through the bores and g and threaded into the same to hold the links in their eye engaging position.

As illustrated in Figures 5 to '7, where the watch casing i is equipped with a loop or staple m, an auxiliary intermediary member is interposed between the staple and the connecting means for the wrist band. This member consists of an eye K1 formed with a tubular, longitudinally slitted 7 member n to be slipped over the staple m.

Figure 5 illustrates the attachment of the tubular member 11. to the staple m, and the engagement of the heads e of the links 0 and d of plate I) with the eye Kl of the tubular member, and shows how the threaded pin h holds the parts in their connected position.

The operation and use of my connecting means will be readily understood from the above description by having simultaneous reference to the drawing.

It will be understood that I have disclosed the preferred forms of my connection only as a few examples of the many possible ways to practically construct the same, and that I may make such changes in the general arrangement thereof and in the construction of its minor details as come within the scope of the appended claims without departure from the spirit of my invention, and the principles involved, so for instance the links 0 and d may be spring-controlled so as to automatically return into their position illustrated in Figures 5 and 7.

Having thus described my invention, what I claim as new and desire to secure by Letters Pat ent is:

1. A means for connecting the ends of wrist watch bands to watch casings comprising a plate to which the band ends are secured, a pair of movable links, projections formed with said links adapted to engage an eye on the watch casing from opposite directions and having bores there- 5 in, and a threaded pin passing through the bores in said links and the eye on the watch casing to firmly connect said plate to which the band end is secured and to which said links are pivotally attached to the watch casing. 10 2. A means for connecting the ends of wrist bands with wrist watch casings, comprising a plate to which the band ends are secured, pivoted and headed links on the band end holding plate, engaging with their heads when swung 15 about their pivots a member on the wrist watch casing from opposite directions, and means passed through said links and their heads and the member of the wrist watch casing to hold and look I the band end holding plate to the watch casing. 20 3. A connection between the ends of the wrist bands for wrist watches and the casings of such wrist watches comprising an eye plate to which the band ends are secured, a pair of links pivotally attached to said plate at their outer ends,

heads formed with said links at their inner ends and oppositely disposed inner projections formed with said heads, said heads and projections having a bore, and threaded means passed through said bore and eye plate on the watch casing when said links are swung about their pivots to engage with their head projections said eye plate on the watch casing from opposite directions to firmly connect the eye plate and band end to said watch casing.

4. A means for connecting the ends of wrist bracelets to watch casings having staples formed therewith, said means comprising a tubular slitted member engaging said staples and having an eye formed therewith, an eye plate to which the ends of the wrist bracelet are secured, a pair of links pivoted to said eye plate, projections formed with said links having bores and engaging the eye of the staple from opposite directions; and a threaded pin passed through the bore in said linkprojections and the eye of the staple to firmly connect the wrist bracelet and watch casing.
